Buy and swap
Sell, gift, or swap copies with other readers. The deal is between people; the app has no checkout.
Print books can keep circulating after you finish them, and these guides explain how. They cover where to sell used books and what each option charges, how to set an honest price based on condition, edition, and demand, how to describe a copy's condition to avoid misunderstandings, and when it makes more sense to swap, donate, or release a book into the wild. They also cover the practical side of dealing with another person: shipping or meeting in person, choosing a safe place, and what to agree on beforehand. On Librarius, selling and swapping put readers in touch with each other; price, payment, and delivery are agreed between them, with no checkout in the app. The guides apply just as well if you sell at a fair, on another platform, or in your own neighborhood.

Sell, swap, or give away books on Librarius
How the reader-to-reader marketplace works: list from your library, tap «Interested», coordinate in chat, and agree on a sale, swap, or gift. No in-app checkout.
Swapping books in person safely
How to meet for a swap or secondhand purchase: approximate map area, public place, do not share your home address, tell someone where you are, and inspect the copy.
How to price a used book (without copying the cover price)
Condition, edition, and demand for an honest price. When to sell, swap, or give away. On Librarius you set the price: there is no checkout.
How to describe a used book's condition (honestly)
Spine, endpapers, highlighting, smell, and clear photos. Why not to say "like new" when it is not, and how an honest listing avoids bad surprises in a reader-to-reader deal.
Shipping or meeting in person? How to close the deal
Costs, package risk, midpoint meetups, and what not to paste in chat. Librarius has no checkout: you and the other reader agree on shipping or an in-person handoff.
